GS8182D19BGD-375

GS8170LW36/72A Sigma RAMs are built in compliance with the Sigma RAM pin out standard for synchronous SRAMs. They are 18,874,368-bit (18Mb) SRAMs. This family of wide, very low voltage CMOS I/O SRAMs is designed to operate at the speeds needed to implement economical high performance networking systems.SRAMs are offered in a number of configurations including Late Write, Double Late Write, and Double Data Rate (DDR). The logical differences between the protocols employed by these RAMs mainly involve various approaches to write cueing and data transfer rates. The SRAM family standard allows a user to implement the interface protocol best suited to the task at hand.
